I dont care for the way SenceUI works so I traded up to the DroidX, I do find the X to be faster, and im talking with everything I use up and running.
Dont get me wrong the incredible is faster than the d1 unless you have one of the few that will run at over 1200mhz, those run pretty quickly but with less mem than the inc or X, you cant have as much running on it.
In all honesty if you prefer senceUI go for it if not i'd consider the d2 or dx both are very fast and have as much ram as the inc, just the motorola's both run the texas instruments cpu.
I run my DX at 1200mhz most of the time cause its rock solid and isn't any hotter than it was with stock voltage at 1ghz. I can run stable at 1350mhz but it does run hotter then.
